摘　　要：研究了离子液体-纳米高岭土复合添加剂对船机设备减摩性能的影响规律,利用HK09型环块式摩擦磨损试验机,研究了两种润滑剂及其混合物在CD40润滑油中的减摩行为,利用扫描电子显微镜对摩擦表面进行表征。结果表明,CD40润滑油摩擦因数较高,最高摩擦因数约为0.11。纳米高岭土颗粒在整个实验温度范围内均有显著的减摩效果。在50~130℃温度范围内,含纳米高岭土颗粒的润滑油摩擦因数稳定在0.04~0.07。离子液体添加剂在90℃下具有最佳的减摩性能,摩擦因数约为0.025。离子液体添加剂与纳米高岭土相互配合,摩擦副的摩擦因数明显降低,在110~130℃高温下,离子液体复合纳米高岭土润滑油添加剂的减摩性能最好,相比CD 40润滑油降低36%左右。减摩机理分析显示,纳米高岭土以微滚珠形式作用于摩擦表面,配合离子液体添加剂对摩擦化学反应的促进作用,使润滑油的减摩性能得到有效提升。The influence of ionic liquid and nano-kaolin compound additive to the friction reduction performance of marine machinery equipment is studied.The friction reduction performance of compound additive is studied on HK09 block on ring test rig,which is mixed with CD40 lubricating oil.The friction surface is characterized by scanning electron microscope,the results show that the CD 40 lubricating oil exhibit the highest friction coefficient,which is around 0.11.The nano-kaolin shows excellent friction coefficient reduction performance around the test temperature range.During 50~130℃,the lubricant containing nano-kaolin show friction coefficient remains stable at around 0.04~0.07,ionic liquid additive exhibits the best friction reduction performance in 90℃,which is around 0.025.Ionic liquid additive with nanokaolin can significantly reduce the friction coefficient of the friction pair.At high temperature of 110~130℃,the ionic liquid and nano-kaolin compound additive has the best friction reduction performance,which is about 36%lower than that of the CD 40 lubricant.The analysis of mechanism shows that the friction reduction properties of lubricating oil is effectively improved,which comes from the micro-ball effect of nano-kaolin acting on the friction surface,as well as the promotion of the tribo-chemical reaction by ionic liquid additives.
